The Oakland Athletics' new Las Vegas ballpark is currently being developed by Bjarke Ingels Group (BIG) in partnership with HNTB and occupies nine acres between Tropicana Avenue and Reno Avenue. The project is part of the franchise’s bid to relocate from Oakland and is being built on the former Tropicana Las Vegas site directly on the Las Vegas Strip.

The project carries an estimated cost of roughly $2 billion and will seat approximately 33,000 spectators. Now, the official Athletics X account has posted an update, revealing that the installation of the third and tallest steel truss arch at the future ballpark had recently been completed.

Construction for the $2 billion project remains on schedule for a 2028 opening as the Athletics continue to play home games at Sutter Health Park in West Sacramento until the move is complete. The design takes inspiration from both baseball and Las Vegas, and the ballpark will span a 9-acre site.

The roof consists of five overlapping shell structures designed to resemble baseball pennants. The stadium's exterior has been designed to visually integrate with the Strip rather than function as a traditional standalone sports venue.

Plans call for a large cable-net glass wall offering panoramic views of the Las Vegas skyline, including surrounding resort properties. Metal cladding on the exterior is expected to reflect both daylight and the city's nighttime lighting to ensure that the structure changes appearance depending on conditions and time of day.

Designers modeled portions of the concept after older ballparks such as Fenway Park and Wrigley Field. Rather than relying on traditional overhead cooling methods, the stadium will distribute air closer to seating areas.

The project is also being positioned as a year-round entertainment destination rather than solely a baseball venue. The move itself concludes a lengthy stadium saga that defined much of the Athletics' final years in Oakland.

The franchise spent decades pursuing replacement options for the aging Oakland Coliseum but failed to secure a long-term stadium solution in the Bay Area. In 2023, Nevada approved a public funding package capped at $380 million through Senate Bill 1, helping clear the path for relocation.
